EPECIFKOATIUN forming part of Lettera Itatent No. 7 83,8326, dated Itehriniry 552th rent, Application filed April l t, 190%. Serial No. 203,156.

Be it known that i, ijiEUjWt] DINKIGL, a eitispecification an iiicien t to enahie others skilled in the art to which the invention appertains to make and use the same My invention relates more particularly to nozzle-sprinldcre for distributing a liquid over theexternai surface of buildings; for protcca tion againat lll'tl, although applicable to other i situations and conditioi'ia of use.'

One object is to protect thediecharge-oriiice from ohatruction; another, to ineure an cllectivc and even distribution of the liquid diacharged.

Vihile not desiring to limit myself thereto, .l herein consider anddescrihe my improved sprinkler as applied for use in connection with a system of stand and branch pipes arranged to protect the windowsv or walls of a building T li-Iercto't'ore trouble has resulted from the clogging up or, ohi-etruction of the diseharge-orii'icee of such nozzles either by reason of the collection within or around such orilices of extraneous matter or by the collectics and aiiord a nozzle or Sprinkler ready tion and freezing of rain-water with the not zle and coinlectione. ll ohvlate these d1il1cul-- "lor innnediate service in emergency in any weather and under all conditions by my involition, which consists in a nozzle Formed and constructed substantially as hereinafter described and claimed specifically, with adeiiecting and protecting hood and with a diechargc-orilice through a plane or surface inclined rearward with'relation to the axis oi discharge, so as to guide extraneous matter away il'Ulll aaid oriiice.

This is aecompiiehed hy tapping the pipe l for the reception oi the nipple a at a rant upon ita imigitmlinal axis.

of the deliector a and constituting therewith a hood are the aide or check pieces (1 c cc-- tween which and the outer extremity oi the deflector n are formed the openings a rior the lateral discharge of the iiquid.

The rear wall or lateral faceoot' the noanlta through which the discharge-orilice o opens, is termed at an angle with relation to the aide of the diecllarge-passage o, the inclined enrface thue produced projecting downward and rearward, so that it will tend constantly to guide d net and other extraneous nnatter away from said (.lischarge-oriiice o.

in the lirst t'onr n'guree ol' the drawings the liquidv escaping under pressure through the oriiicc'o impinges against the outer extremity or tongue o of the deflector o and is thereby diverted in the fori'n'oi' aehectot spray which i triltee the side of the huilding or other aurlace to be protected below the nozzle, which usually arranged a few inches t'roln auch inn-face. in the preferred form shownin Fig- 5 and c the under surface of the deflector at a concave parabolic curve of which the edge of the tongue 1/" ii; the vortex and the liquid controlled and guided ininn-diatcly upon leaving theorii'icco and until dischargtal from the nozzle, the result being auhatantially the aame in either case, except that in the lallcr form a more unil'ornily-diatrihntcd unhrolmn ehect of eprayis diachargcd continuously from the nozzle, since the reaction ronacqm nt to the impact of the liquid with the deflecting-anri lace is iu-utralizoil, the change oi direction l heing cli'ertcd gr.-ulualiy and uniformly.

The collection and freezing of rain-water within the nozzle is practically impossible, as would be the lodgment of any foreign matter within the hood,

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with a pipe, of an open sprinkler secured" thereto with the discharge from said pipe through the sprinkler at an an gle to the surface to be protected, said sprinkler having depending side pieces forming a hood, and a flat downwardly-inclined deflector 20 at the outer end of said sprinkler with side discharge-openings for the lateral discharge of the liquid betweensaid hood and deflector.
